What Defines a Cell? Figure 1: Transport proteins in the cell membrane A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment. Each transport protein is specific ...

What is a cell membrane in conjunction with biology? What is the fluid that fills the membrane bound cell and contains the organelles? Which cell organelles control most of the activities of a cell? Which organelle is present in the cells of a mouse but not present in the cells of a bean...
The endoplasmic reticulum helps in the manufacture of fat molecules or lipids. These proteins and lipids help in the building of the cell membrane. This process is known as membrane biogenesis.

A cell can replicate itself independently. Hence, they are known as the building blocks of life. Each cell contains a fluid called the cytoplasm, which is enclosed by a membrane. Also present in the cytoplasm are several biomolecules like proteins, nucleic acids and lipids. Moreover, cellular...
In biology, a simple example of a permeable membrane is a cell wall. In both plant and animal cells, the cell wall is a permeable membrane that allows the passage of particular substances while preventing others. This is known as semi-permeability. ...

@indemnifyme - The plasma membrane was one of my favorites in biology too. Once you learn about the plasma membrane, a lot of other stuff about the cell is easy to understand. For example, once you've got the idea of membrane proteins down, passive and active transport are easy to unde...
